' Application filed September 2,1914. Serial No. 35?,92t). c: Y I a T0; a llvwhome't-mag f concern Be it known that I, DONALD BARNS {MOBI- SON, a subject-of the King of Great Britain and Ireland, residing at Hartlepool, in the county i of Durham, England, have invented Apparatus .for WVithdrawingpAerated Vaporand Condensate from Steam-Condensers, of whichthe following-isletspecification.

This invention relateslto apparatus- 0f the kind" described and referred to in thezspecifieation .of application Serial .No. 85,9481 wherein, aerated vapor, is withdrawnfrom a steam condenser hya steam 'jetkand vis discharged into ,areceiver into which .a-regulated quantity ofboiler feed water isad- .mitted for the purpose of condensing the steam from thesteam jet, the heated water being withdrawn from the receiver separately at 'a higher-temperature than the aerated vapor, the air pressure or air density ofthe aerated vapor being increased by the condensation of the vapor {by another portion of the boiler feed water of a tem- 'peratur e lower than that discharged from the receiver, thus 'decreasingthe volumeof a given weight of air and reducingflthe size of the air pump andtthe power necessary to ,diseharge the air to the atmosphere The systemaccordingto the present invention maybe applied to surface or jet condensers, and consists ,in withdrawing the aeratedvapor and'heated water from the receiver into which the steam jet discharges .by vone or more reclprocating pumpsin'xthe manner described in the 1 speclfication hereinbefore referred to, ,the condensate from the condenser being withdrawn separatelyby "a rotary .pump.

.A feature of the lnvention is that apparatus for artificiallycooling the water whlch condenses and cools the aerated vapor, is

.not required, therefore there are no dangers resulting from leaks such: as Imay occur m with artificially cooled Water 'inwhichethe cooling agent 1s sea water. 'Moreover, the

weight and space occupied ,:areereduced,or ialternatively, 7 if the size of the ,pumps 1s I maintained the number of strokesper minute i can be reducedpthus reducing wear and tear.
